Class 100 Clean Room Cabinet Ovens
Class 100 Clean Room Cabinet Ovens
For processes where eliminating particle contamination is required, such as sterilization, depyrogenation, curing and drying. These electrically heated ovens feature a low particle count Class 100 atmosphere inside. Exterior construction minimizes particle generation. Heavy duty units equally suited for pharmaceutical or industrial applications.
Class 100 Clean Room Cabinet Ovens Model Specifications:
CAUTION: Ovens processing combustible material are required by National Fire Protection Association 86 Standard for Ovens and Furnaces (NFPA 86) to have a fire suppression system. If flammable solvents or vapors are present in an oven, OSHA requires conformance with NFPA 86 Class A Oven requirements. A powered forced exhauster and other non-standard safety equipment must be added. See Class A Oven Equipment for Solvent Processing resource page, reference our FAQs or contact us us for more information.
